To all whom it' concern.'

Be it known that I, Gnonon ELDRED VAN FossEN, citizen of the United States, and

resident -of Frederick, in the county Aof- Letters Patent of the United States No.`

920,588, dated May 4, 1909, such patented mechanism comprising a tuft guide or casinor mounted to swing in a vertical plane towar and from the brush back in timely relation to the vertical reciprocations of the tuft-inserting slide, the lower forward end of the guide or casing being provided with a toe or projection which,when the guide 1s swung downward into position for the tuft-insertmg operation, pushes back the adjacent seated tuft and provides a free passage for the new tuft to the brush back. Said patentedy mechanism permits the filling of the back in only one direction of movement of the latter, that is, from left to right or from right to left, as the case may be.

The object of my invention is to rovide simple and eficient mechanism w ich is operable to form the individual tufts and guide them to the brush back and also to push out of the way of the entering tuft the previously-inserted tuft, irrespective of the direction of movement, to the right or the left, of the brush back below the tuft inserting element.

To this end my invention comprises va rious novel features of construction and combinations of parts which will be hereinafter described and claimed.

In the drawings- Figure 1 is a side elevation of a brushmachine embodying a preferred form of my invention, only so much of the machine being shown as is necessary to illustrate the improvements. In this view the tuft-guide is illustrated in raised position on one side of the vertical.

Fig. 2 is a similar view, partly inv section, showing the tuft-guide in its central or active position.

Fig. 3 is a sectional elevation of a por.-

tion of the machine, as viewed from the I side opposite to Figs. land 2, the guide belng shown in a raised position opposite to that shown in Fig. 1.

Fig. 4 is a side elevation, on an enlarged scale, of the tuft-guide and associated parts as shown in Fi 3, but viewed from the opposite side of t e machine.

Fig. 5 is a horizontal sectionthrough the reversing slide-bar and its accessories, as on the line 5-5 of Fig. 4.

Fig. 6 is avertlcal section through the tuft-guide and its associated parts, the guide being shown in central position and the tuftsetting slide being illustrated in down osition and with a tuft seated thereby 1n a brush block.

Fig. 7 is a perspective view of an oscillatory lockin arm hereinafter described.

Fig. 8 is aiorizontal section through the supporting structure, on a plane above the tuft-guide, asv on the line 8`8 of Fig. 6.

Fig. 9 is a perspective view of the tuftguide and its appurtenances.

Referring to the drawings, 10 designates the supporting frame; 11 the drive shaft of the machine, and 12l the ber magazine. A single delivery `magazine is shown; but, of course, a plural delivery magazine, and its appurtenances, such as described in Patent No. 920,588 aforesaid, may be employed.

13 designates a horizontal shaft which is driven from the drive shaft by means of a lbelt 14 passing around pulleys 15, 16 on the respective shafts.

17 designates one of the tables on which the blocks 18 to form the brush-backs are supported and by which they are fed ,to the boring and tuft-inserting devices. 'Innthe present instance, the table is illustrated provided with holding devices for twoopf positely-inclined adjacent brush blocks',.so that one of the bored blocks may beconvefr'i iently in reserve While the other is-b'eing filled with tufts, as seen in Fig. 6. 19 designates the horizontally-reciprocaL tive slide by means of which quantities; 0f fiber are successively separated from the mass in the magazine. and fed into positi for insertion as tufts into the adjacent bored block on the table 17. The slide herein illustrated comprises generally a long bar having a suitably-disposed .cut-out portion into which extends one end of a laterally insert piece 20 on the bar so as to provide a vertical opening 21. The free end of the insert piece is formed with an overhanging lip 22 which is desi ed, as the slide is moved beneath the magazlne, to engage a `quantity of the over` lying fiber and to force it down into the` lthe tuft by the inserting devices. Pivoted to one end of the bar is a link 26 which is connected through a spring-controlled frame 27 with a lever 28 in engagement with a cam 29 fast on the shaft 13, whereby the slide is longitudinally reciprocated to move its fiber-receiving portion 21 beneath the magazine and adjacent the tuft-inserting devices alternately.

30, 30' designate the vertically-reciproca-y tive slides which in each successive downward stroke are relatively operated to form a wire staple and in conjunction therewith to insert and secure a tuft of fiber in a hole of the bored block. The mechanism for operating the slides includes a rock-lever 31 which is connected at its ends with the slides andwith a crank-arm 32 on the shaft '13 by means of links 33, 34 respectively.

35 designates a lower horizontal shaft which is driven lstep-by-ste through suitable connections actuated rom the upper shaft 13 which connections include a ratchet wheel 35 fast on the sha-ft 35; a rock-arm 35?. bearing a pawl 35a in engagement with the ratchet wheel and an eccentric 35* mounted on the shaft 13 and connected by means of a rod355 with the rock-arm. lThe shaft 35 carries a cam wheel, the peripheral cams 36 of which, through suitable trans-y mitting devices, effect the requisite trans verse, vertical and longitudinal movements of the work-holding tables in order to 'position the brush-blocks with respect to Vthe boring and tutt-inserting devices. The transmitting devices include ahorizontallyreciprocative frame 37 under the influence of the cams 36 and carrying a vertical in 37 extending through a longitudinal guide structure 372 which is operatively connected with the brush table.

No detailed illustration or description of the various mechanisms above indicatedv is Bof deemed necessary herein as such mechanisms are or may be of the character described in the Lebherz Patent No. 920,588 aforesaid;

and also in the Young Patents Nos. 57 8,90 and 664,989 dated March 16, 1897, and Jan'- ua 1, 1901, respectively, referred to inthe aai Lebherz patent.

bodying my present invention comprises a.

tapering tubular casing 38 of the general shape most clearly illustrated in Figs. 6 and 9. The vertical opening 39 of this structure for the passage of the slides 30, 30 and the associated staple and ber, is re duced from top to bottom so that the fiber, during its descent, is doubled into tuft form about the lower end of the slides. rlhe base of the structure is rounded as shown and is provided at its respective ends with oppositely-projecting toes 40. The casing is affixed to a bracket 41 which is fast on one end of a horizontal shaft 42 journaled in a suitably-disposed bearing bracket 43 on the main frame. On the opposite end of the shaft 42 is loosely mounted a rocker-arm 44 which is frictionally held in position on the shaft by means of a friction washer or cap 45 fastened to the end of the shaft so as to bear against the arm. Hence by actuation of the rocker-arm as hereinafter described the casing may be positioned vertically with its opening in axial alinement with the slides 30, 30 and may be oscillated on either side (right or left) of the'vertical, as desired. The arm 44 is connected by means of a link 46 with one arm of a crank.- lever 47 which is ivoted'on the main frame, the other arm o the lever being held in operative contact with a cam 48 fast' on the shaft 13, by means of a yspring 49 which is secured at its ends to the lever and frame respectively. The contour of the cam 48 (Fig. 2) is such that the crank-lever 47 is,

ally-inclined position, the.' swing beingeither to the right or the left of the vertical, so that the leadingtoe or projection 40 will press back the opposing tuft in theblock as may be re uired by the direction of motion ofthe brus block, viz, from right to left or vice-versa. A vertical guide piece 50 l affixed to the frame guides the horizontal arm of the crank-lever. l

Fast on the bodv of the shaft 42 is a head having two oppositely-extending arms 51 which are adapted during the shaft 42 to abut against the opposinr frame plate 52, and thuslimit the upwarmovement of thearms, and, perforce, the extent of rotation of the shaft, to the righ or left as desired. y

0n the shaft 42 adjacent the hub of the rocker-arm 44 is an 'arm 53, termed a lock-4 ing arm, having at its outer end a projection comprising a radial tooth 54 and a laterally Aprojectingshoulder 55, the latter-bein arranged to overhang and contact wit an arched cam surface 56 formed on the hub end of the arm 44, in such wise that the locking arm partakes of the oscillatory motion of the m 44. ze oulder 55 bears upon the rotation ofizo f y menace and has capacity for relative rocking move'- I menton the cam surface 56 in such a manner that ifthe locking arm be ridly held in up-standing vertical position other of the cam surface 56 and thus tend to maintain the locking arm, together with the.tuft-casing, in vertlcallysdepending 1 arm 53 is in vertical position. This plate 57 is guided at its vertical edges` in spacedapart guide bars 59 depending from the frame structure. The upper end of the plate is connected by means of a link 60 with one arm of a rock-lever 61 which is ivoted on the main frame, the other arm o. the lever bearing a roll 62 which is maintamed 1n operative contact with a cam 63 on the shaft 13 by the action of a spring 64 which 1s secured at its ends to the lever and frame, res ectively. (See Fi 2). The contour of t e cam 63 is Asuch t at when the arms 44, 53 are swung to vertical osition the plate 57 is depressed to enga e t e rnotch v58 wlth the u -projecting toot 54 of the arm 53 and t us centralize said latter arm and lock it in position. The contour of the lower 'portion of the cam edges 58 of the plate is such as to permit the free rotation of the tooth 54', lduring the vertical movement of the lplait/e, and the contour of the up er portion of the cam ed es is such as to e ect and insure the centra izing movement of the tooth in respect to the notch 58. In the descent of the horizontal arm of the cranklever 47 above referred to to eect the downward swing of the arm 44 and the concurrent iipward swing of the arm 53, such lever arm bears upon the shorter arms of a pair of spaced-apart gravity crank-levers 65 which are ivoted on the guide bars 59, as at 66, the onger depending arms of said crank-levers thus being swung toward each other. These longer arms are so disposed in spaced relation to each other that when the are swung inward they move into the at of travel of the radial tooth 54 of the roc erarm 53 through the respective lateral arcs,

that lever-arm adjacent the upturning tooth bearing against the latter and insuring its movementy beyond the projection 67 formed at the juncture of the upper and lower portions of the proximate cam edge 58. The levers 65 thus perform the function of a safety device. (See Fi 2.)

On the lower ends of the epending members of the plate 57 are laterally projecting pressure blocks 67 for a purpose hereinafter explained.

e shoulf4 der will bear upon one inclined face or thef-`4 to right, below the' insertin j whetherA the movement of the rush block be longitudinal or transverse of its major axis, as determined by the operation of the table, the relation-of thetuft-casing' and its co-'operating partsv is such that the casin swings in an arc to the right or to the le t of the vertical, as thecase may be. When the casin is locked in vertical position the fiber is I bent into tuft-form, and inserted into the brush block. When the casing swings to the right or tothe left, as thedireotion of movementof the brush block may dictate, the

lcasing esca es the tuft thus seated, the block is advance a step, and the casing is returned tovertical position preparatory to the In such return' movement the leading toe 40 of the casin insertion of a new tuft.

imfpinges against the previously inserte tu t and pushes it to one side so as to ensure a free unobstructed passage for the next succeeding tuft through the casing to the brush block, and so on. v j

An oscillatory plate 68 having in its upper edge a recess with oppositely-inclined `ends constituting spaced-apart abutment shoulders 69, is pivoted, as at 71, to a horizontal slide bar l72 mounted in guides 73 on a pair of'depending brackets 74. The guides are preferably provided with antifriction rollers 75 for the slide-bar. plate 68 is rovided adjacent one end with an arcuate sllot 76 into which freel extends from the bar 72 a pin 77 whic co-acts with the respective ends of the slot to limit the extent of vertical oscillatory movement of Vthe plate. lThis plate is preferably pro vided o n one side, near its respective outer corners, with sockets 78, with opposite airs of which spaced-apart spring-pressed .ook-

ing pins 79 slidably sup orted in the bar are adapted to register, w en the plate is in either inclined position, right or'left, thusv temporarily locking the plate in place. (See Figs. 4 and 5). Y i

On the inner face of the plate 68, adjacent its respective ends, are two .laterallyrojecting studs or rolls` 80, the spaced reation of which to the respective blocks 67 on the bifurcated locking plate 57 is such that when the bar 72 isv in the right hand position shown in Figs. l and 2, the right hand block impinges against the opposmg right hand stud 80 of the plate 68- and presses the adjacent end of the latter downward, thus throwing u ward the left hand end of the late' 68 an positioning its left hand shoul er 69 inthe path of rotation of the lower end of the rockerarm 44, and that when the bar 72 is shifted to the left as shown in Fig. 4, the left hand block 67 impinges against the left hand stud 80 of vDuring the step-by-stepvmovement ofthe brush'block from right to left or from left The riven down through .the casing,

the plate 68 and reverses the angularity of the latter, thus ositioning the right hand shoulder 69 in the path of rotation of the rocker-arm 44.

When the plate 68 is in the right-inclined position the link 46 is inclined downward to the right of the vertical, thus, by the movement of the crank-lever 47, swinging in an arc on Vthe ri ht-hand side and correspondzontal slide-bar 86 which is guided in a suitingly oscillating the arms 44, 53, the shaft 42 and the tuft casing 38. ln such position of che plate 68, its right hand shoulder 69 is below the path of the rocker-arm 44, thus permitting the motion of the latter. When,

owever, the plate 68 is moved to the left and shifted to the left-inclined position as above described, the right hand shoulder 69' impinges against .the opposing lower portion of the rocker-arm 44 and thus swings the latter to the left of the vertical. The link thus being inclined downward to the left swings in an arc on the left-hand side and correspondingly oscillates the arms 44, 53, the shaft 42 and the tuft casing 38. In that case the left hand shoulder 69 is below the path of the lower portion of the arm 444 so as to permit the free swinging motion of the latter. -When the plate 68 is again moved to the right the right-hand operation of the arm 44 and its appurtenances is repeated, and so on.

After the last tuft of' each row has been inserted in the brush block, the bar 72 is shifted to the right or to the left as may be required by-the next succeeding or return movement of the brush block; that is to say, when the block is moving from ri ht to left the bar 72 is in the position in icated in Figs.l 1 and 2; but upon the lcompletion of the row of tufts and preparatory to the movement of the block from left to right, the bar is shifted to the left as indicated in Fig. 4.

rIfhe reversing bar 7 2,' as vit may be called, is automatically shifted at predetermined intervals by mechanism of the following character: Une end of the bar is connected by means of a rod 81 to the upper armv of a lever 82 which is pivoted on a suitably-disposed bracket 83 on the main frame. A spring 84 securedto the upper lever arm and to the adjacent bracket 83, tends normally to ull such arm and therewith the bar 72 to t e right hand position illustrated in Figs. 1 and 2. The lower arm of the lever 82 is jointed to the upper'arm of a lower lever 85 also pivoted on the bracket 83. The lower arm of the latter lever 85 is jointed lto ahoriable bracket 87 arranged on the main frame and adjacent the shaft 35. On this shaft is a wheel 88 provided with a cam 89 (or a series of spaced-apartsimilar cams) into the path of rotation of which extends a laterally projecting stud or roll 90 on the slide-bar lmally in the path of thev spu Memes 86, said cam being so formed and ositioned that as it rides against and passes t e stud or roll 90 the bar 86 is forcibly retracted and then released. When the bar 86 is retracted the combined levers 82, 85 are swung in opposite directions to each other on'their respective fulcra, against the action of the spring 84, similarly to a toggle-joint, thus pulling the reversing bar 72 to the left. When the cam passes the stud or roll 90 the slide-bar 86 is released, but by means of suitable locking mechanism such bar is maintained in retracted osition until the next succeeding row of tufts has been formed and inserted in the brush back. rlhe particular locking mechanism herein illustrated comprises a latch lever having a hook-shaped arm 91 which is movable into and out of locking relation to a Spud 92 on the bar 86. A spring 93 secured to the other arm 94 of the lever maintains thehook-sha ed arm nor- 92, so that when the slide-bar 86 is retracted as above described, the Spud passes under the hooked arm and is engaged thereby; the bar 86 thus being securely held in the retracted position. The lever arm 94 is jointed to the lowerarm of avertical lever 95 which ispivoted, as at 96', ou the bracket 87, the upstanding arm of the latter lever having a stud rroll 97 located inthe path of rotation of a cam 98 (or a series of spaced apart similar cams) on y' the wheel 88. VThe .cam 98 is arranged in spaced relation to the cam 89, so that at a predetermined interval afterythe retraction of the slide-bar 86 the cam 98 impinges against the opposing stud or roll 90 and swings. the upper arm of the lever forcibly to -the right, thus moving the latch lever and disengaging its hooked end fromthe spud 92, whereupon the slide 86 resumes its previous position to the right.

The general operation ofthe foregoing described tuft-inserting and guiding lnechefi v' o owsfm, L l

anisms may be briefly explained as The table for the borey blocks A'beingsup plied with blocks and being brought to a predetermined starting point for. the filling-f," of one of the blocks with tufts, the hori# zontally reciprocative slide` 19 functions to take the required amount of liber from the ns p magazine 12 and carry it to a position for transference to the path ofthe verticall reciprocative slidesV 30, 30', which latter, 1n their initial downward movement and prior to receiving the ber, form a wiresta le,

.which as it descends with the slides strad les the fiber and serves as a means to fasten the tuft in the block as usual. Simultaneously Leonesa y inserted. Coincidentally with the downwar swing of the tuft casing the bifurcated plate 57 descends, being actuated by the cam 63, rock lever 61 and link 60. The motion of the plate is so timed that when the tuft casing is in the vertical position (as seen in Figs. 2 and 4), the central notch 58 of the plate 57 engages the radial tooth 54 of the arm 53 and thus locks the arm and its adjuncts, including the casing, 'in that position; and the contours and relative position of the cams 4.8v and 63 are such that the tuft casing and its actuating and loclng mechanism are caused to remain stationa during the reciprocation of the tuft-inserting slide 30.

Upon the' return of the slides 30, 30 to their uppermost position the cams 63 and 48 again become active, the former cam causing the bifurcated plate 57 toascend and thus release the tooth 54 of the arm 53, and the latter cam effecting the upward swin of the tut casing either to the right or le t as required by the direction of travel of the brush block being filled. The upward movement of the casing clears it from the fiber of the tuft last inserted `in the block and.

allows the free movement of the work either longitudinally or transversely as the case may be, to bring the next adjacent hole in the block to the filling position. This done the above described cycle of operation is repeated, and so on.|

-The direction of travel of the tuft-casing 38 which, on its upward movement, is away from the previously filled portion of the block, is controlled by the position of the oscillator late 68, the function and operation o w ich, together with its associated parte, have been hereinbefore fully explained.

The track ortravel of the brush 'block to position its holes for the rece tion of the succeeding tufts may be varie as circum- A stances may require, and in accordance therewith vthe swing of the casin may be either longitudinal or transverse o the major axis of the block, the casing operating to push previousl inserted tufts clear from the path of the tu which is bein inserted re ar less of the direction of trave of the bloc Although in the construction herein 'illustrated the tuft-casing, is mounted to swing longitudinally of the normal plane of the brush block, it is obvious that the axis oi oscillation of the casing can be chan ed in order to vary the path of motion of t e caeing; that is, the casing canbe mounted to swing transversely of or in different angular relations to the normal plane of the brush block.

It is to be understood that I do not limit my invention to the particular construction herein disclosed, as the mechanism can be modified in various respects within the rinciple of the invention and the scope o the appended claims. claiml 1..
